Abstract

We consider finite Bernoulli convolutions with a parameter 1/2<r<11/2 < r < 1 supported on a discrete point set, generically of size 2N2^N. These sequences are uniformly distributed with respect to the infinite Bernoulli convolution measure νr\nu_r, as NN tends to infinity. Numerical evidence suggests that for a generic rr, the distribution of spacings between appropriately rescaled points is Poissonian. We obtain some partial results in this direction; for instance, we show that, on average, the pair correlations do not exhibit attraction or repulsion in the limit. On the other hand, for certain algebraic rr the behavior is totally different.
